You're tracking the drums in the same room as the N12?!
Good luck with that technique.
If not, you're doing something else wrong.

Dude! do you have anything nice or productive to post? The guy said absolutely nothing about tracking drums in the same room. And what is wrong with doing that? He can use the mixer as a drum stool, if it works for him.

And he was commenting to MY post about the mixer headphone output being poor. Although you seem to be the only one that don't have an issue with that...
